In the year 23 BBY, Griph, desiring membership within the Black Sun, found themself in an Ord Mantell planet cantina alongside their Twi'lek lover. Griph informed their partner that their uncle possessed connections to the Black Sun and believed the syndicate might accept them; however, their conversation was cut short by Boba Fett, a young bounty hunter still in training, who had been commissioned by the Twi'lek's father to bring her back home.
